Hi all,
I am trying to configure my printer to use the bltouch that I just added and have noticed that if I add the G29 code to the startup G-code in S3d that the extruder cools while the auto bed leveling is happening. If anyone can answer:
1. Is there a G-Code that I can put in after the G29 command to have the extruder brought back up to the proper temp?
2. Is it possible to completely change the startup sequence of the printer (e.g. move the G29 in between the commands to heat the bed and the extruder)?
thanks,
dave
Re: extruder cooling after autobed leveling (G29)
You presumably loaded a new firmware (and you're using Marlin) configured for the BLTouch, right?
You'll find that #define PROBING_HEATERS_OFF is uncommented and causing the heaters to turn off.
It is here:
https://github.com/MarlinFirmware/Marli ... ion.h#L742
Regarding changing the order of stuff, yes you can.
In the starting gcode script you can add in the following lines and it'll do the heating there:
M104 S[extruder0_temperature] T0
M140 S[bed0_temperature] T0
When you change that and save the gcode, make sure you go open the gcode file and just double check that everything is in the order you want, and that the placeholders have been replaced by the real values.
